Application led December permit leeding; of ruw gas or the like charge to the engine.

A `liurther object isy to provide a footoperated device ot this character which is mounted upon the dash-hoard of un automobile sind in which the foot pedal is readily adjustable to differ angles 'for the purpose of adapting the device to machines of dit ferent types. lt is likewise on object to construct n device of this character which muy he readily atlsched. to the usual dash-hoard with c rnparotively slight alterations in the dash-hoord eonstruotion end readily 'etteclied to the operating crank ot the usual butterfly vulve without any alteration What- ,Vith the foregoing and minor Objects in view. the .invention resides in the novel subrnetter hereinafter described and oleimed, the description being supplemented by the necoinpsnying drawing.

Figure l is a eideelevetion illustrating the supplication of my invention;

Figure e side eleva-tion showing' my "ico in idle position; "ingiurie il is a. similar view showing;` the positioned to close the usual butterfly 'gr-ire l ie :i fragmentary front elevation i automobile dashboard showing` my in Ive tion mounted thereon; and

Figure 5 is a sectional view taken substantielly on line 5--5 of Fig. 2.

'lt is understood that this construction is readily adaptable to fuel inlets ot feed devices ot dilerent types, though Jfor the purpose of this application l have .shown it associated with a carburetor ot 'the usual form employed in connection with the Ford type ot internalcombustion engine, this car hureter including the usual air inlet I which has e. lnittertly control valve 2 provided with e lever 3 Wliioh muy lio readily operated from the radiator, not shown, by ineens of in operating rod i which. extends forwardly trein the oerloureter. My invention is adapt ed to he mounted upon the dashboard .of

on. automobile :it e point adjacent the foot hoard 6, and broadly consist-s of o bell crank, one end ot which 1s so formed es to serve 24, 1ers. sez-.iai weer as a. foot pedal, while the other end connected Ito the aforementioned butterfly operating lever 3. A. spring; device 1s arranged in connection with this hell crunk lever so eo as to normally retain the butterfly vulve El 1n open pos1tion.

In mounting this apparatus upon a deshfhoard 5, the letter is provided with e. vert-L cel slot 7 about Whose inner end is arranged e5 e tace plate 8 carrying transversely .alined hearing members or eure 9 for the rereption of a transversely urrenged pin 01' stub sha1 t 10 as shownin Fig. 5. This plete is fixed to the dashboard 5 by means of bolts or any To otherI suitable fasteners l1. It will he noted in Fig. 2, that the ears or hearing` members Q oro arranged adj acont the lower end of the Slot I so that when the hell crank isin its normal position, the lower end Well l2 ot 'I5 the Slot will serve es fr stop und limit the downward movement ot the forward end ol said. bell crank.

` The bell cronlc consists ,ot a. relatively short erin i3 provided near its rear end 8u with n transverse openingF in which is received the aforementioned stun shaft or cross pin 1G, the vouter endet this arm 13 being turned downwardly and apertured for a purpose to be pointedout. The opposite 36 end of this hell crank is provided with n disk-lille head upon one Side ot which is forinedo-set ot lethal-teeth or serrations 14 which extend radially from atriunsverse.

openingE l5 alined,vvitli u. similarly 'formed 90 opening 1G in a disk head l? carried zit one end ot a foot pedal or lever 18 ns shown in Figs. and 5. A screw bolt or the like 19 eonneetstho pedal 18 end the erm 18 and hos o knurled linger-piece :20 by means of which 95 said elements may be readily separated either entirely or a sufiicient amount to permit relative angular adjustment. It will oe noted fili that tlrolioad l? oli the toot pedal 18 is also provided with serrations or radial 100 teeth 17 which conch with the nforemeir tioued teeth to positively lock the pedal 18k.. and tlie'arn'i 1S et any preferred angle. It." is understood that itwill be quite advantageous to embody this adjustable feature in this l apparatus, since through this adjustment, the apparatus .may he readily adapted to difteront types of machines in which the dash li'ourds and itoothoerds are .relatively dil-V 'erently positioned. ,deshboard 5 serves as er stop .for limiting; 'the inward movement of the pedal l8 itllurther, since the M0 While other ypes of spring naturally follows that the degree of ibis movementJ controls the extent to which the buitery valve 2 is actuated and consequent- 1y, the operator may predecermine the excent or movement of the buticrfiy valve by changing; the relative angles of the lever or foot pedal 18 and the arm 13.

FixedY to the downwardly turned end 21 of the arm 13.is a link comprising a peir of transversely spaced arms or bars 22 which are pivoted between their ends to lle outer portions of a transverse pin 21 carried by the. downurned portion 2l. 'ihe lower end or this link device yis connected to the nppei end of the connecting rod 23 whose lower end is pivoted to the butteriy valve operating lever 3 as shown in Fig. l..

devices may be employed to retain ihe parts in the posisions shown in Fig. 2, I'preferably pivotally connect e head 2i to the upper end of ihe aforementioned link, ihis head carrj'iing a.

`guide rod or stein :25 about which is arranged y,

The normal position of this apparatus is shown in Fig. the forward end of fixe arm iii bein-'y conizzacii with ille sto portion l5?,
